Embodiment Construction

[0071] Performance evaluation of asphalt pavement of underground roads is the basis for decision-making of urban road maintenance management. On the basis of investigation, the service performance of urban underground road pavement is analyzed, and the service performance evaluation index and evaluation standard of underground road asphalt pavement are put forward. It is more objective and can provide effective scientific decision-making for road maintenance and repair departments.

Abstract

The invention relates to the technical field of underground road bituminous pavement service performance evaluation. In order to make the evaluation result objective, the effective scientific decision can be provided for the road maintenance and repair department. In order to fulfill the aim, the adopted technical scheme is as follows: the entropy weight-based underground road bituminous pavement service performance evaluation method comprises the following steps of: 1. determining a composite underground road pavement performance integrated evaluation index system, namely 1.1. determining evaluation indexes and evaluation standards, 1.1.1. determining underground road bituminous pavement damage condition evaluation indexes and standards, 1.1.2. determining composite underground road pavement driving quality evaluation indexes and standards, and 1.1.3. determining composite underground road pavement safety performance evaluation index and standards; 1.2, establishing a comprehensive evaluation model; and 2. performing a composite underground road pavement service performance evaluation method. The method is mainly applied to the underground road bituminous pavement service performance evaluation.

Description

technical field [0001] The technical field of performance evaluation of asphalt pavement of underground roads of the present invention, specifically, relates to a performance evaluation method of asphalt pavement of underground roads based on entropy weight. Background technique [0002] With the development of our country's economy and the continuous enhancement of the technical level, underground roads have been widely used in many cities. Underground roads are the transportation hub connecting the two places. Performance and aesthetics all play a vital role. Once a disease occurs, it will often affect the normal passage of urban traffic, and it is difficult to maintain due to limited space. Therefore, the underground road surface is required to have a long life. Therefore, how to comprehensively evaluate and predict the performance of asphalt pavement in underground roads has never been studied in depth at home and abroad, and there is no unified standard. Therefore, it ...
